Clearing Records in FlashForm Grid

["jsmith031308" <webforumsuser@xxxxxxxxxxxxxx>]

I have a flash form with two grids.  When the user clicks on a row in the top 
grid, the bottom grid is loaded with related data.  My customer wants the 
bottom grid to empty out between top grid row clicks--while the new recordset 
is being fetched for the bottom grid.  How is this done?  I do not know 
ActionScript, but since the page is already using a block of ActionScript 
within <cfsavecontent> tags, I can paste it in.
